Dueling Dresses: Kim Kardashian vs. Rihanna!

Kim Kardashian is at it again with her copycat couture … and her latest muse is Rihanna!

The reality star donned a navy blue Givenchy dress while shopping in West Hollywood with her mom, Kris Jenner and new beau, Kanye West, on July 13.

Kim paired the curve-hugging number with Christian Louboutin python heels and layered gold necklaces. She styled her hair in a slicked back ponytail and wore considerably less makeup then we’re used to seeing on the 31-year-old. Perhaps at the request of Kanye?

RiRi sported the elegant ensemble one week earlier while leaving her hotel in Manhattan. The Grammy winning-songstress styled her outfit with gold necklaces, metallic open-toe heels, and her hair done up in a bun. The pop star was morning the death of her grandmother, hence the more conservative look.

So who wore it better? We have to give this one to Rihanna. Kim’s dress doesn’t really flatter her figure and we’re not loving her nude lip. But Rihanna’s makeup, hair and heels are perfection – she looks both classy and chic!
